John Mount points out that there is a built-in function to mutate data frames in R:

The notation we used above is the “explicit argument” variation we recommend for readability. What a lot of

`dplyr`

users do not seem to know is: base-`R`

already has this functionality. The function is called`transform()`

.To demonstrate this, let’s first detach

`dplyr`

to show that we are not using functions from`dplyr`

.`detach("package:dplyr", unload = TRUE)`

Now let’s write the equivalent pipeline using exclusively base-

`R`

.
